Oil ear is very annoying? Actually, dry ears are the genetic variation.

Professor Yang Xichuan, Original Professor of Xichuan Xiaoliang Dermatology

People with sharp ears, it’s too difficult to be a real wife!

My ears are oily and my earwax is wet and sticky. Every time I take off my headphones, the sticky lump on them makes people almost die on the spot …

In the end, why is there an oil ear, one of the most annoying bugs in the human body? Is there really nothing you can do with greasy ears? Don’t worry, just look and you’ll know ~

Why are there oil ears?

Earwax (cerumen) is the secretion product of cerumen sweat gland, which can be divided into wet (oily) and dry.

Dry earwax, which lacks earwax secretion, is dry and fragile, and its color ranges from light gray to brownish gray. On the contrary, wet earwax with strong cerumen secretion is usually wet, sticky and dark in color.

Auricularia auricula is most common in Africans and white Europeans; Dry ears are most common among yellow people in East Asia (especially Koreans, Chinese and Japanese) and Native Americans.

(The black part is the oil ear gene, and the gray part is the dry ear gene)

Oil ear does bring some troubles, which makes people envy the freshness of dry ear, but few people know that oil ear was originally a "palace" and dry ear was a "concubine" later.

Our human ancestors were all oil ears at the earliest, and dry ears appeared because of gene mutation in the process of continuous evolution (just as people with body odor are normal, people without body odor are actually genetic mutations).

The "cold adaptation hypothesis" shows that the environment of the ancestors of East Asians is much colder than that of Africans. In order to adapt to the cold climate, the ancestors of East Asians have gene mutations, which reduce sweating and sweat secretion.

The cerumen gland belongs to one of the apocrine glands, and the secretion ability of cerumen gland decreases, so there is dry ear.

Do you have body odor if you have oil ears?

Our sweat glands can be divided into apocrine glands and apocrine glands. Body odor is the odor emitted by axillary apocrine glands (apocrine sweat glands) after sweat is degraded by bacteria, which is manifested as peculiar smell, excessive sweating in armpits and clothes dyeing.

The auricularia auricula is formed by the exuberant secretion of cerumen gland in apocrine gland, increased oil and mixed dust and dander.

Both oil ear and body odor are mainly regulated by the 538th base of ABCC11 gene in the middle of chromosome 16, so body odor and oil ear usually coexist. People with body odor usually have oil ear, but people with oil ear do not necessarily suffer from body odor.

Can oil ear be inherited?

Oil ear and dry ear conform to Mendel’s genetic law. Whether you are oil ear or dry ear is determined by genes.

G/A and G/G genotypes belong to the wet type (oil ear), which belongs to the dominant inheritance like dimples and double eyelids. And A/A is a dry type (dry ear), which belongs to recessive inheritance.

That is to say, if the father is an oil ear (G/A, G/G) and the mother is a dry ear (A/A), then the child may be an oil ear or a dry ear (the probability of oil ear is high).

Both parents are oily ears, and children are more likely to be oily ears and less likely to be dry ears; If both parents have dry ears, the child must have dry ears.

Can you pick out your ears? How to care?

Cerumen, that is, earwax, which is formed in the outer two-thirds of the ear canal, is a normal substance and physiological phenomenon existing in the external auditory canal. It has the functions of protection, moistening, antibacterial and so on, and will also be discharged by itself through ordinary behaviors such as chewing food, talking and coughing.

Therefore, under normal circumstances, oily ears and dry ears do not need to be treated, and cotton swabs should not be used to dig into the ear canal to avoid ear canal obstruction caused by pushing ear wax deep into the ear canal.

If you feel that the oil ear is really uncomfortable or affects the appearance, you can occasionally gently wipe the mouth of the external auditory canal.

(The green part is cerumen, which is located 2/3 outside the ear canal)

Otitis externa, ear canal stenosis, ear canal trauma, the use of hearing AIDS or earplugs or the use of cotton swabs to dig out the ears may all cause ear canal obstruction, thus causing cerumen embolism.

Embolism usually leads to a series of consequences: tinnitus, fullness, itching, earache, secretion, odor and cough, and even reversible hearing loss.

Studies have shown that 10% of children, 5% of healthy adults and more than 30% of the elderly and people with developmental retardation have cerumen embolism.

(cerumen is completely stuffed in the ear canal)

If cerumen embolism occurs repeatedly, you can go to the otolaryngology department of the hospital to see if it needs to be treated.

Treatment methods include observation, dissolution with cerumen dissolving agent, washing, manual removal except washing, and combined method (for example, washing after earwax is dissolved; Rinse and then remove manually).

Manual removal includes the use of curettes, probes, hooks, tweezers or direct observation under headlights, otoscopes or microscopes.

Finally, do a little research. Are you oily or dry? Does it bother you? Take a walk in the comment area ~ by the way, click to watch+share, and help friends around you solve their troubles ~

New mothers are the most lonely, and nearly 90% have lost their social life.

   


  The new mother left most of her time to her children.


  Having children is something to be happy about. But a recent survey in Britain found that women who are first-time mothers feel most lonely in the first year after their children are born. The main reason is that they have no time and energy to contact relatives and friends during childbirth and maternity leave, thus being out of touch with the outside world.


  Nearly 90% lost social life.


  The British "Mom and Baby" magazine and Tesco Supermarket Co., Ltd. jointly conducted a survey on about 2,000 new mothers with an average age of 29. It turns out that many of them need to work hard to adapt to the new identity of "mother".


  About two-thirds of new mothers said that they lived far away from their mothers and had little contact with them. In addition, they basically lost contact with other relatives, friends and colleagues. More than half of new mothers feel "lonely and isolated". Among the women surveyed, on average, each person has only 90 minutes a day to get in touch with people except their husbands and children, and the rest is given to the children.


  Many new mothers say that after the birth of their children, most of the quarrels between them and their partners are due to this-they are "lonely and isolated", but their partners work or engage in social activities as usual.


  Caused by modern lifestyle


  The survey results said: "Less than 30% of new mothers’ mothers can help look after their children, while one third of new mothers’ mothers-in-law never help look after them."


  British media reported that the lifestyle of modern society is that people live farther and farther away from their relatives and friends, which makes motherhood more challenging.


  "Being away from work, giving birth to children has an arduous physical and psychological adaptation process for women. This is a brand-new life, which is completely different from what they used to live." Dalrymple, editor of Mommy and Baby magazine, said.

Micro-observation of current politics | The future of a country lies in the youth.

  "Youth is like early spring, like the morning sun, like the germination of flowers, like the new development of a sharp sword, and the most precious period of life."

  More than a hundred years ago, Youth Magazine was founded and later renamed New Youth, which had a far-reaching influence. In that stormy era, a group of new youths held high the torch of Marxist thought and searched hard for the future of national rejuvenation.

  For more than 100 years, China has never stopped exploring the road of modernization. General Secretary of the Supreme Leader pointed out that the Chinese dream of realizing the great rejuvenation of the Chinese nation cannot be separated from the relay struggle of generations of young people.

  On June 22nd, the 19th National Congress of the Communist Youth League of China was successfully concluded. The General Assembly mobilized and led the youth members to unite and struggle for building a socialist modern country in an all-round way and promoting the great rejuvenation of the Chinese nation in an all-round way.

  It will take one or two generations to achieve the goal of the second century from now until the middle of this century. General Secretary of the Supreme Leader emphasized that the young people of China in the new era are born at the right time and shoulder heavy responsibilities.

  What kind of young people can be so responsible? What would they look like if they painted portraits of new youth in the new era?

  — — The appearance of fighting bravely for the first place.

  On June 19th, Fu Qiaomei, a researcher at the Institute of vertebrate paleontology and Paleoanthropology, Chinese Academy of Sciences, was awarded UNESCO — Al-Fazan International Award for Outstanding Young Scientists in Science, Technology, Engineering and Mathematics.

  Fu Qiaomei has been engaged in paleogenetics research for a long time, mainly focusing on ancient DNA to explore important scientific issues of human origin and evolution. As one of the leading scientists in the field of international paleogenetics, Fu Qiaomei stood out from 2,500 candidates around the world and became the first China scientist to win this prize.

△ On September 11th, 2020, General Secretary of the Supreme Leader listened to the speeches of seven representatives of scientists, including Fu Qiaomei.

△ On September 11th, 2020, General Secretary of the Supreme Leader listened to the speeches of seven representatives of scientists, including Fu Qiaomei.

  "People often ask, ‘ What’s the use of your research ’ . When it was difficult to maintain the laboratory, I also thought about whether to do hot research. " In September, 2020, when talking with the General Secretary of the Supreme Leader, Fu Qiaomei expressed her confusion.

  The general secretary said: "What do you think of the unpopular? Generally speaking, some unpopular things are useless. This understanding may delay the career in a field. To evaluate scientific research, we must have a long-term vision, a world vision and a scientific vision. "

  Fu Qiaomei was deeply inspired. She led a young team and made continuous breakthroughs in research, pushing China’s ancient DNA research into the forefront of the world.

  A generation has the fate of a generation, and a generation of young people has the mission of a generation of young people.

  On May 4, 2013, General Secretary of the Supreme Leader came to China Academy of Space Technology of China Aerospace Science and Technology Corporation to participate in the theme group day.

  After 90′ s, Pei Xianfeng became a skilled welding technician in just a few years through diligent study and hard practice, and won the silver medal in the welding project in the World Skills Competition, achieving a breakthrough of zero medals in Chinese.

  The general secretary praised: "through hard work, your youth career is highly compatible with the cause of the party and the country and the cause of the people, so that the spectrum of your career will be broader and the energy will be stronger."

  "Mozi", "Tian Wen" and "Chang ‘e", young scientific and technological talents can be seen everywhere in these undertakings entrusted with the dream of national rejuvenation — — The average age of the core staff of Beidou satellite team is 36 years old, the average age of quantum science team is 35 years old, and the average age of Five-hundred-meter Aperture Spherical Radio Telescope (FAST) FAST R&D team is only 30 years old … …

  The General Secretary of the Supreme Leader encouraged: "We should look at the innovation and creation of young people with appreciation and approval, actively support them to shine in life, and praise and applaud the achievements and achievements of young people."

  — — Not afraid of hardship

  Do you choose a stable life in Beijing, or do you choose to go back to the countryside to "suffer"?

  Wei Qiao, a young man born in 1980s, gave her own answer: She used to be an assistant researcher at the Institute of Geography of China Academy of Sciences. Six years ago, she and her husband both quit their jobs in the Chinese Academy of Sciences and Peking University, and returned to their hometown in Jiangsu to plant more than 20,000 mu of rice. Through digital management, the yield per mu reached 1,100 Jin, which effectively promoted the surrounding farmers to become rich.

△ Wei Qiao spoke at the plenary session of the Jiangsu delegation at the First Session of the 14th National People’s Congress.

  During the National People’s Congress this year, Wei Qiao told the Supreme Leader General Secretary about his experience. After hearing this, the general secretary was very appreciative: "It’s good for a comrade like Wei Qiao to go to the countryside!"

  Suffering hardships is also the choice of the supreme leader in youth. In Liangjiahe, Shaanxi Province, farming, pulling coal, damming and picking dung … … He has done almost everything. Looking back on those days, he wrote in "I am the Son of the Yellow Land", "Difficulties and hardships can temper a person’s will. The hard life of going to the countryside for seven years was a great exercise for me. Later, when I encountered any difficulties, I remembered that I could still work under such difficult conditions at that time. Why not do it now? "

  In Zhengding, Hebei Province, he rode his bicycle all over every village in the county, got a solid and detailed understanding of the county situation, found problems and collected public opinion. He said that he was ready to enter the "sea of suffering"; In Xiamen, he volunteered to take charge of the work concerning agriculture, rural areas and farmers, and made full use of all forces to promote the development of poverty-stricken areas … …

  Today, the young people in China in the new era are in the best period of the development of the Chinese nation, and they are faced with the rare life opportunity of making great achievements, as well as the mission of the times.

  In youth, if you choose to suffer, you choose to gain, and if you choose to give, you choose to be noble.

  When inspecting the Youth Cave in Hongqi Canal, Anyang, Henan Province, the General Secretary emphasized: "The younger generation should inherit and carry forward the spirit of hard work, self-reliance and hard struggle, abandon arrogance and arrogance, and engrave their youthful blood on the historical monument like our parents."

  In a reply to the students in the Science and Technology Academy of China Agricultural University, the General Secretary encouraged everyone: "You said in your letter that only when you go deep into the local China can you deeply understand what is seeking truth from facts and how to contact the masses, and young people will ‘ Ask for it ’ That’s very good. China youth in the new era should have this spirit. "

  Just as General Secretary of the Supreme Leader said in a discussion with outstanding youth representatives from all walks of life ten years ago, "It is good for you to experience a little more beatings, setbacks and tests in your youth."

  — — Aim high.

  Su Yiming, who won the championship in Beijing Winter Olympics, wrote a letter to the Supreme Leader General Secretary after the game.

  Soon, he received a reply from the general secretary — — "I hope that your hearts are tied to the motherland, your ambitions are high, your feet are on the ground, you will create a wonderful life in your struggle and contribute your youth and strength to the motherland and the people."

  The paper is short-lived and long-lasting, and the hope is infinite. Youth’s ideals and beliefs are related to the future of the nation.

  In July, 2021, Huang Haifen, a Chaoshan girl born after 1990s, met the Supreme Leader General Secretary who was investigating in Xizang. At that moment, her heart was pounding with excitement: "I am a university student village official. I graduated from Guangdong University of Finance and Economics four years ago and always wanted to do something for the frontier, so I came to work in Linzhi."

  The general secretary asked with concern: "Will you stay here in the future?"

  Huang Haifen said shyly, "Stay! Settle down, my lover is in the next village and came to Xizang together. "

  The general secretary encouraged her: "From the coast to the plateau, people are needed here. You should do well here."

  Hearing the general secretary’s words, Huang Haifen nodded with tears in his eyes.

  A life with faith, dreams, struggle and dedication is a meaningful life. Generation after generation of young people have integrated their "small goals" into the "big blueprint" of the cause of the party and the country.

  "In the new era, young people in China should establish their belief in Marxism, Socialism with Chinese characteristics and the Chinese nation’s great rejuvenation of the Chinese dream, go among the people and go to a new era and a new world, so that ideals and beliefs can be sublimated in entrepreneurial struggle and youth can shine in innovation and creation!" This is the ardent expectation of the Supreme Leader General Secretary to the contemporary youth at the conference commemorating the centenary of the May 4th Movement.

Louis Koo’s "Searching for Qin" is expected to start in March. Jessica Hester Hsuan: Still changing the script

1905 movie network news According to Hong Kong media reports, actress Jessica Hester Hsuan said at an event on February 20th that the film version of "Searching for Qin" is expected to be officially launched at the end of March this year, but she revealed that she has not seen the final script yet.


"Because there is no script yet, I have been changing it, and I want to make it better. When I was having dinner with my friends, the other party put forward some opinions. I think I would tell Gu Zi (Louis Koo) if I could." When asked whether the movie version continued the story of the TV series, Jessica Hester Hsuan immediately responded: "The old boss won’t let me talk!"


As early as 2015, it was reported that Louis Koo prepared and negotiated for the copyright of the novel "Searching for Qin" and prepared to shoot a film version. He also intended to invite Du Qifeng to be the director, but he was not satisfied with the script and never put it into shooting.In 2016, the news came out again that the film would start shooting in Inner Mongolia in 2017, and LAM Raymond, Jessica Hester Hsuan and other original people all returned, but in early 2017, Louis KooDeny the news,It means that the project is still in the stage of script creation.


In March 2017, Huace Film Company obtained the novel copyright of Searching for Qin, officially announced that it would jointly produce the film version of Searching for Qin with Tianxia One Film Company founded by Louis Koo, and exposed two concept posters at the same time, and then announced that the film would be directed by the new director Li Zhenlong, and there was no news about the filming. Four years later, can the film version of Qin Xun Ji really start shooting as scheduled? Triggered speculation.

IE, it’s time to redefine the browser.

  ◎ reporter Liu Yan

  After 25 years, Microsoft Internet Explorer is about to "retire", and another digital product has faded out of the stage of science and technology history.

  From June 15, 2022, some versions of Windows software will no longer support the current version of IE 11 desktop applications.

  There is glory and word-of-mouth decline.

  IE is a graphical user interface web browser developed by Microsoft, and it is one of the most important tags in the Internet era. Without rivals and the system itself, IE browser peaked at birth, and its market share was as high as 95% at one time.

  On August 24, 1995, Microsoft was in Windows 95 Plus! The first IE browser was launched in Pack — — IE1.0。 The cleverness of Microsoft lies in bundling it into the operating system and offering it to users for free. Two years later, IE browser occupied 49% market share.

  Binding policy is not the only reason why IE browser dominates the rivers and lakes. IE browser is the first supporter of many technologies commonly used in web pages now, which makes web pages more interactive and attractive in visual effects, and competitors are left far behind.

  For example, because IE browser supports AJAX at the bottom, web pages can display the latest information from server data without refreshing. This concept is very important for highly interactive websites such as Gmail and Google Maps.

  However, with the advent and continuous progress of Firefox, Google Chrome, Apple Safari and other browsers, users have made comparisons and choices, and a large number of market shares of IE browsers have been seized, with the share falling below 20% in 2015.

  On April 29th, 2015, Microsoft announced the launch of the Edge browser at the Build conference, and encouraged users to stop using IE and switch to Edge. IE browser began a long farewell.

  Talking about this alternation between the old and the new, Microsoft replied to the Science and Technology Daily reporter: "The development of the Internet has surpassed the evolution of IE browser. Considering the new Web standards and innovation requirements, we need to build a new browser. Compared with IE browser, Microsoft Edge can bring a faster, safer and more modern Web experience to Internet users. "

  Microsoft emphasizes that Microsoft Edge with IE mode is the only browser with built-in support and compatibility with websites and applications based on IE browser.

  In other words, the Edge browser solves a key problem. IE functions such as developer tools and ActiveX controls can be called in the Edge browser, and users can directly access the old websites and applications based on IE from the Edge.

  There are changes and the future is unpredictable.

  On August 17th this year, the last major version of IE browser, IE 11, will cut off Microsoft online services, such as Office 365, OneDrive and Outlook.

  Luo Haoyuan, co-founder of Sino-Guangdong Investment, believes that IE’s suspension of service has no effect on ordinary users. The long-term service channel (LTSC) of Windows 10 will still support IE browser, so the operation of websites such as enterprises, institutions, governments and banks that only use IE browser at present will not be affected.

  Shi Lei, the former founder of WPDang, told the Science and Technology Daily reporter: "Edge’s connection with IE comes naturally, which is in line with Microsoft’s development plan. Judging from the basic technology construction of Edge browser based on Chrome, not everything in Microsoft is based on its own standards. "

  In Shi Lei’s view, Microsoft is the most basic standard setter, or at least the main participant in standard setting. It doesn’t matter to Microsoft which kernel the browser uses. HTML language is a standard that Microsoft participated in, which is enough. Just as whether windows and office are used or not is not so important to Microsoft, as long as ntfs (a disk format supported by a series of operating systems of Microsoft Windows NT kernel and designed for network and disk quota, file encryption and other management security features) or even the lower file system and office document format are common formats in the industry, it will be beneficial to Microsoft.

  "IE curtain call and Edge, Microsoft is still that Microsoft, and it is still a top technology company." Shi Lei said, "It is alive and well. The company that raises scientists will not make big mistakes and can afford the cost of trial and error."

  However, the hero’s late death still attracts countless sadness. The feeling of "Ye Qing Hui" and "Ye Qing Jie" is not only the memory of many people touching the Internet for the first time, but also the doubt about the future direction of the browser, which was the absolute overlord of traffic portal in the past.

  With the application and cloudization of PC, mobile phone and other devices, the meaning of "portal" has fundamentally changed. Without the browser, it will not affect people’s shopping, social interaction, games and entertainment, and the scenes generated by the browser will become less and less important.

  Luo Haoyuan said: "The focus of competition has shifted from entrance to time. Whoever takes up more users’ time has greater value."

After graduating from college in 2011, he was assigned to TISCO Precision Belt Company as a production worker. At that time, the technology of "hand-torn steel" was monopolized by Japan, the United States and other countries for a long time, and the price of a piece of A4-sized "hand-torn steel" was 400 yuan. Even if the price is so expensive, the domestic demand for related materials often falls into the situation of "cooking without rice".

Faced with the urgent need for high-tech basic materials in major national strategies and key emerging fields, in 2016, TISCO’s "hand-torn steel" innovative R&D team was established.

However, it is not an easy task to make "hand-torn steel". It is necessary to ensure steel purity, production line technology, control level, high-grade surface accuracy and product performance. These are like mountains in front of everyone.

Facing the difficulties in the industry and challenging thorny issues is undoubtedly a hot potato for many people. After all, before this, the core technology of "hand-tearing steel" has never been systematically studied by any team in China.

However, as the employee who is most likely to roll out 0.02mm "hand-torn steel" in China iron and steel enterprises, Duan Haojie became one of the first 15 R&D team members of TISCO and began to grow together with "hand-torn steel" for five years.

Repeated failures challenge the limits.

As thin as cicada wings, the thickness is only 0.02 mm "hand-torn steel".

As thin as cicada wings, the thickness is only 0.02 mm "hand-torn steel".

Shanxi people like to eat noodles, rolling noodles, waking noodles, mixing noodles and cutting noodles … … In all the processes, rolling noodles is the most important, and the thickness of noodles is directly related to the taste and appearance.

In order to make "hand-torn steel", four difficulties must be overcome: rolling, annealing, high-grade surface control and performance control. In the whole process, the rolling of the first process is the most important link. Just like rolling, the steel strip is thinned from thick to thin, which directly affects the thickness and quality of "hand-torn steel".

As the person in charge of production, looking at the two precision rolling mills in the workshop, how to install the rollers, how to set the middle spacing and let them "roll" thin and tough steel has become the most difficult problem in front of Duan Haojie.

"There are six choices for 20 rollers corresponding to different widths, and five choices for taper. Each taper corresponds to five different taper lengths, and at the same time, different convexity choices need to be taken into account. The ratio of so many variables means more than 20,000 possibilities. " Duan Haojie said that in all complicated rolling processes, broken belt is the most "collapse".

At 9: 00 am on December 10, 2017, the rolling mill carried out 0.02 mm piercing rolling according to the predetermined plan. At 11: 40, the threading was completed. When the rolling production reached more than 100 meters, there was a loud bang, and the steel strip was instantly broken. Unlike the thick plate that broke the belt in two, the thin plate was broken into powder at that time.

In Duan Haojie’s office, there is a stack of work notes more than 1 meter high, which records all the research and development data and rolling methods of "hand-torn steel".

In this way, from 0.1 mm to 0.05 mm, and then to 0.03 mm, the foil is getting thinner every day. After 711 tests, 175 equipment problems and 452 process problems were overcome. At the beginning of 2018, a 0.02 mm ultra-thin stainless steel precision foil that challenged the limit, broke foreign monopoly and filled domestic gaps was finally successfully developed and made its debut in the world.

Once this kind of steel that can be torn by hand came out, it broke the people’s inherent impression of steel, became an instant hit and became popular on the Internet.

Strive for the spire and look forward to the future

In fact, no one is born as a "schoolmaster". For Duan Haojie, it is common practice to take the factory as his home and the data as his companion.

At 7 o’clock every morning, Duan Haojie, wearing a red helmet and blue tooling, will quickly walk into the No.8 workshop of Jingdai Company. Here, he spent the most stressful but also the most brilliant decade of his life.

In the interview, Duan Haojie said that his favorite word is "toughness". In his view, "tenacity" is a combination of time and mental effort. It not only has flexible wisdom from softness to rigidity, but also represents his own inner pursuit, which is the spirit he yearns for.

"What I did made up the industrial chain ‘ Breakpoint ’ , let ‘ Buy at a high price ’ Change ‘ Fair price ’ , more solved ‘ Get stuck in the neck ’ I am very proud of the problem, which is also the meaning of my work. " Facing the honor and praise, Duan Haojie said that in addition to "hand-tearing steel", many high-end stainless steel products they developed and produced have been used in nib steel on the nib, carbon fiber in the aerospace field, Hong Kong-Zhuhai-Macao Bridge and so on.

Without first-class skilled workers, there would be no first-class manufacturing industry. The breakthrough of "tearing steel by hand" is a microcosm of the profound transformation and structural optimization of China’s steel industry.

What the heart wants, the line will come.

In September 2020, Duan Haojie and his team members successfully mass-produced the "hand-torn steel" with a thickness of only 0.015mm again, breaking the previous record of "hand-torn steel" with a thickness of 0.02mm..

The birth of new products has created greater economic benefits for enterprises, provided sufficient confidence and strong self-confidence for China to accelerate the construction of a manufacturing power, and demonstrated the hard-core strength of China manufacturing in terms of technological achievements such as technical research and technological innovation.

Confidence and dignity of Chinese films: a "small renaissance" of literature and art at the end of the summer file

    1905 movie network exclusive feature At the end of August and the beginning of September, just as the vigorous summer file created a record of 12.4 billion yuan in gold, three films with literary attributes released at the same time stepped on the tail of the summer file also entered the first round of fermentation of market inspection.

 

    After the "Troika" which was called "Big Mac" in July and the unexpected opening of the situation, many fans finally regained their confidence in Chinese movies. The appearance of "scorching sun" and "hidden mother" at the end of August, although doomed to be unable to compete with traditional commercial films at the box office, made people see the dignity of Chinese films. The topics that accompany several works are endless and worth pondering.

 

Competing on the same stage: is the performance of the three cities in the hot sun good or bad?

 

    As of September 1, the box office results of movies, movies and movies were 162 million, 46.95 million and 11.15 million respectively. This figure is really not outstanding in the Chinese film market where the box office is over 100 million in the first week. But comparing the box office results of several directors’ previous works, there is no doubt that this is an optimistic start.

    Especially for director Cao Baoping, this achievement has condensed too much emotion and bitterness. When Cao Dao’s debut was released in 2007, he had negotiated with the distributor to make 70 or 80 copies and invested 1.25 million yuan to promote the film. As a result, the other party "broke the promise", and finally only spent 20,000 to 30,000 yuan to make two copies. Cao Baoping was so anxious that he made two more copies, and finally used four copies to spread the national cinema. How can you imagine its box office results? Think again that there were only more than 13 million people who have missed the audience so far. Now, "Burning Heart in the Hot Sun" not only won the grand prize at the Shanghai Film Festival, but also created many topics.

 

    For Hou Hsiao-hsien, a willful author and director, Nie Yinniang the Assassin, as its first work to land in a mainland cinema, is even more rare. This film with an investment of 90 million RMB from the mainland can be regarded as Hou’s most expensive work, and to some extent, it can also be regarded as Hou’s work that considers the audience’s feelings. The award-winning aura of Cannes has made the mainland young people who owe Hou’s movie tickets have been hungry for a long time, not to mention that it is the legendary "last Chinese film movie", so the significance of this unique work landing in the mainland cinema today is by no means just a box office figure that can be estimated.

 

    Compared with the above two works, A Tale of Three Cities directed by Zhang Wanting seems to be not dazzling in word-of-mouth and box office. Although some events in recent days have slightly enhanced the topic of the film, the film still lacks the courage to be independent. Some fans even suspect that the husband and wife files are too far from the time when they were filmed, and the film has become+,and these two films are far from expectations in word of mouth and box office.

 

Tite for tat: ordinary young people don’t realize that literary youth "retaliate" to watch movies

 

    "The world is getting worse, starting with Wen Qing being teased." In view of the film Assassin Nie Yinniang, some "unconscious" ordinary fans joked that "the language level was damaged by 10 thousand physical points" and "the picture was too beautiful, but I was not allowed to take screenshots"; Even more poisonous tongue fans spit out that "showing off literature and art as food will lead to famine", "If the film is suitable for holding hands with people you like, you will be excited for a month" and "I can’t tell whether it is a movie or a PPT”… …

 

    Correspondingly, Hou Dao’s veteran fans have completed three brushes and four brushes in less than five days, and even gathered friends and relatives to hold a group, and their enthusiasm is no less than that of the "tap water" of the Great Sage. However, compared with the "bursting" behavior of the "tap water" who blew up the circle of friends, the literary youths who supported Hou Xiaoxian were obviously much more calm.

 

    This is reflected in the following aspects: most of the shared content is about the expanded interpretation and historical background of the film; Hou Hsiao-hsien’s works review, director style, etc., too emotional personal feelings are very rare; Even after some "ordinary audience" left the scene halfway and kept playing mobile phones, film critic Tao Taolin told us clearly that "I don’t want to recommend Nie Yinniang, because I don’t want people who don’t know Hou Xiaoxian to torture other audiences because they don’t like it."

 

    On the one hand, it is not difficult to see the great aesthetic difference of the audience, on the other hand, it also shows that the information coverage of the film is indeed considerable. As of September 1st, the author has personally watched this film in three different cinemas (Dongzhimen Broadway Film Center, Ciyun Temple Yaolai Jackie Chan International Studios, Xidan Capital Cinema). Although the audience really couldn’t stand the long shot and the half-written dialogue, the attendance rate of the film was much higher than expected. For the vast number of mainland audiences, whether they like it or not, at least let them see another possibility of movies.

Association: Tesla China delivered over 77,000 vehicles in May and entered the era when products were king.

  "Too strong to be ridiculous" is no exaggeration to describe Tesla.

  In the past month alone, in the real investigation and rating of authoritative organizations around the world, Tesla has been in the forefront with significant advantages in many rankings such as performance events, brand value and business indicators.

  In terms of performance, Model Slaid successively set two world records: New Bogeling North Ring Circuit, which set the fastest electric car lap speed record with a score of 7 minutes, 25 seconds and 231 milliseconds; 1/4 mile acceleration, promoted to 8.73 seconds, breaking the previous record of 8.834 seconds.

  In the brand field, Boston Consulting Group (BCG) announced the list of the most innovative companies in 2023 last week, and Tesla became the highest ranked automobile brand in the world, and ranked second in the overall list, up three places from the previous year.

Association: Tesla China delivered more than 77,000 cars in May, and the products entered the king era _fororder_image001.

  The innovation of product technology has not only made Tesla continue to be favored by consumers around the world.

  On June 5th, the Association released the estimated sales volume of new energy vehicles, and Tesla Giga Shanghai delivered 77,695 vehicles in May, up 142% year-on-year. If there is no accident, it will once again surpass BMW, Mercedes-Benz and Audi and win the domestic luxury car delivery champion.

  In the global market, Tesla also performed brilliantly. According to the data of overseas analysis organization JATO Dynamics, Model Y broke the myth of Toyota Corolla’s fuel vehicle, topped the sales in the first quarter of 2023, and took the first place in the industry as a pure electric vehicle, creating the history of the travel industry.

  When more and more intelligent electric vehicles can meet the increasingly rich needs of life, who will choose fuel vehicles as "functional vehicles"? Electrical travel led by Tesla has become the general trend of the times.

  Model Plaid has set two world records in a row, and the promotion of referral benefits can reach 7000 yuan.

  Behind Tesla’s "Top One" in the world is solid product strength.

  As a "benchmark" product in the field of travel, the new Model S and Model X have always maintained a leading edge in performance and intelligence. In recent days, Model Slaid has successively set two world records.

Association: Tesla China delivered more than 77,000 cars in May, and the products entered the king era _fororder_image002.

  A few days ago, at the North Ring Circuit in New Bogeling, which is known as the "touchstone of automobile performance", Model Slaid equipped with racing kit broke the fastest lap time record set by Porsche Taycan Turbo S one year ago with a time of 7 minutes, 25 seconds and 231 milliseconds (7:25.231). In the industry, New Bogeling North Ring Circuit is often called "an incredibly difficult high-speed track", with a vertical drop of 300 meters and 177 bends.

  Not only that, Model Slaid also improved the measured acceleration of 1/4 mile to 8.73 seconds, and staged "surpassing yourself", refreshing the world’s fastest acceleration record of 8.834 seconds created before.

  According to Tesla official website, the top speed of Model Slaid can reach 322km/h. You know, at present, the take-off speed of ordinary civil airliners is about 200 km/h-300 km/h. In other words, driving Tesla is faster than when the plane takes off.

  Model X Plaid also has extremely powerful performance, with a 100-kilometer acceleration of 2.6 seconds, which is enough for rivals at the same level.

Travel Association: Tesla China delivered more than 77,000 vehicles in the auto market in May, and the products entered the king era _fororder_image005.

  In order to further let domestic consumers experience the "benchmark" performance, on June 3rd, Tesla announced through official website that the "Treasure Box" time-limited gift package was delivered!

  Before June 30, as long as you order a brand-new Model S/X through a friend’s recommendation and pick up the car, the car buyer can get a recommendation incentive of 7,000 yuan to deduct the final payment of the vehicle. At the same time, car buyers can enjoy the 90-day free trial right of the enhanced automatic assisted driving function (EAP) and the 3-year free use right of Tesla super charge distributed in the same period.

Travel Association: Tesla China delivered more than 77,000 vehicles in the auto market in May, and the products entered the king era _fororder_image006.

  As a referrer, if the referrer successfully takes away the Model S/X, he can also get the treasure chest points that have increased several times — — 48,000 points. Points can be exchanged for super charging mileage, TeslaMic wireless microphone, children’s walkers and many other selected good things.

  Tesla, which has invested more than 95% of its resources in R&D and production, has never let consumers down.

  0 behind advertising, tamp down technology research and development, summer travel shows the hard power of "smart car"

  "Products are the best advertisements."

  Just as the company has always insisted, Tesla, with 0 commercial advertisements, has won a good industry reputation and wide market recognition by solid technical accumulation.

  Last week, the Boston Consulting Group (BCG) announced the list of the most innovative companies in 2023. Tesla became the highest-ranked automobile brand, ranking second in the whole list, up three places from the previous year.

  Undoubtedly, technological innovation is the driving force of enterprise development. Automatic assisted driving, OTA air upgrade, in-vehicle entertainment system, active safety function & HELIP; … The accumulation of these forward-looking intelligent technologies in Tesla has led the "oil to electricity" to become the general trend.

Travel Association: Tesla China delivered more than 77,000 vehicles in the auto market in May, and the products entered the king era _fororder_image007.

  Take the summer car as an example. Compared with the fuel car, the smart enough electric car can meet consumers’ demand for more cars.

  For example, Tesla owners can remotely set the air conditioner through the mobile App, which reduces the waiting time for pre-cooling the cabin, and adds intelligent functions such as dog mode and overheating protection to match more abundant daily car scenes.

  When traveling in summer, more and more car owners also use actions to prove that electric vehicles can not only run long distances, but also go to places where fuel vehicles can’t reach. Chun Sen, the owner of Tesla, who arrived at the foot of Mount Everest, proved that pure electric vehicles not only have better performance under long-distance and extreme weather conditions, but also lead fuel vehicles in many dimensions such as environmental protection travel and energy replenishment cost.

  Not long ago, the contents of the "2022 Impact Report" released by Tesla showed that in terms of energy efficiency, the Model Y all-wheel drive version is about 6.4 km/kWh, which is by far the most efficient SUV;; In terms of car ownership cost, measured by the overall life cycle of the vehicle, the ownership cost of Model 3 rear-wheel drive version is about 2.08 yuan/km, which is similar to that of Toyota Corolla and far lower than that of BMW 3 Series, a luxury fuel vehicle with the same starting price. Model 3 is also the first electric vehicle in the industry with the same price as a fuel vehicle of the same class.

  In the home charging scenario, Tesla’s 100-kilometer electricity bill is only 10 yuan, and the maintenance expenditure is only 1/2 of that of a fuel vehicle; In the decade from 2012 to 2022, the actual battery life of Model S also increased by 50%. At present, all S3XY models can be recharged for 15 minutes, which can supplement the battery life by more than 250 kilometers — — In other words, Tesla can fully charge the power needed for commuting in a week with only one cup of coffee.

  It can be said that Tesla is the breaker of automobile development for a hundred years. On the wave of new energy transformation, it leads the whole industry with powerful intelligent technology, reliable safety capability and intimate car service.

  There is no doubt that Tesla with strong technical capabilities should have been the first choice for consumers. (Photo courtesy of Tesla)
